Just because you've locked your bike to a streetlight doesn't mean it's safe. All that's required is a man with a big enough pair of industrial pliers, and it's goodbye bike, hello bus home.

The solution? Lock your bike up 10 feet high. How? We'll show you how.

The mid-air solution comes courtesy of German company Conrad, which has devised a contraption that clamps around lampposts and crawls its way up to the unreachable height -- making it inaccessible unless, of course, you have the remote control.

So what you do is pin your bike on the hookymajig, and up it goes, chugging skyward. It's only a prototype, but it's bound to have plenty of Internet oddballs ordering a dozen or two.

Check out how they did it, why they did it and the contraption in action below.
